Sometimes after publishing changes are not available in live

Sometimes after publishing changes are not available in live. We have to delete the bin and re-publish to fix the issue, when we check the box Delete every time and publish but it takes too long.

So someone from IT department has to manually delete the bin folder and publish to fix the issue.

This happens for both javascript changes or code changes. This often happens for User controls.

Please advise how do we fix this.

Thank you in advance.
